1N6673R

Overview

The Microchip Technology 1N6673R is a military-grade standard recovery rectifier qualified under MIL-PRF-19500/642. It features a 400V reverse voltage rating and supports an average forward current of 2A in a DO-201AE (DO-4) axial leaded package. The device operates within a junction temperature range of -65°C to +175°C, ensuring reliability in harsh environments.

Feature Summary

• Qualified per MIL-PRF-19500/642 for military applications
• Hermetically sealed glass passivated junction
• High thermal stability with extended operating temperature range

Applications

• Military aerospace power supplies
• Avionics rectification circuits
• Harsh environment electronic systems

Procurement Notes

Verify the specific qualification level (JAN, JANTX, or JANTXV) required for your design, as suffixes denote different testing standards. Confirm RoHS status, as military variants may not be compliant. Request the latest datasheet and PCN documents to ensure component continuity and manufacturing origin accuracy before finalizing procurement.

Selection Notes

Select this component when high-reliability rectification is required in space-constrained axial packages. Ensure the circuit design accommodates the 400V peak inverse voltage limit. Consider the thermal management requirements for continuous 2A operation at elevated ambient temperatures up to 175°C junction temperature.

Part Context

This part belongs to the 1N66xx series of standard recovery rectifiers manufactured by Microchip. It is designed for general-purpose rectification in demanding conditions. The R suffix typically indicates a reel packaging option for automated assembly processes, distinct from bulk packaging.

Replacement Considerations

Direct replacements include other MIL-PRF-19500/642 qualified diodes such as the 1N6673AR. Verify pinout compatibility and electrical parameters like reverse leakage current and forward voltage drop before substituting.
